LAMP FOR MOTOR-CYCLES.

Specification of Letters Patent.

Patented Aug. 27, 1912.

Application filed March 7, 1912. Serial No. 682,160.

To all whom it may concern:

Be it known that I, JOHN W. ERICKSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lamps for Motor- Cycles, of which the following is a specification.

This invention relates particularly to improvements in what are commercially known as tail lights for motor cycles though the device which forms the subject matter of this application may be used for illuminating purposes in other connections than that of a motor cycle or similar machine.

The especial object of the improvements embodied herein is to produce an illuminating device or lamp of such construction and arrangement that it may be readily connected with a supporting structure such as the mud guard of a motor cycle or a wheel guard of any kind, and in which danger of breakage from the vibration to which such lamps are commonly subjected. will be reduced to a minimum.

A further object of my improvements is to produce a lampof the character described that will serve to project rays of light from the vehicle and also toward a sign or number plate such as are commonly used on m0- tor cycles and similar vehicles, so that such sign will be adequately displayed without interfering with thesignal functions of the device.

A further object of my improvements is to produce a device of the character stated of such-compact construction that it will not project but slightly from the. surface of the member to which it is secured, and thus the danger of having it struck or having it interfere with the operation of the vehicle or the movements of the rider will be reduced to a minimum.

A still further object is to produce a device of the character stated in'which the lamp body proper and the bracket which forms the attaching means for the device integrally thus giving greater economical manufacture of same.

A still further objectis to produce a device which may be interchangeably used for gas or electricity as the illuminant.

In the accompanying drawing which forms a part-of this application, I'have illusthe device and conserving the trated my device in a preferred form in the following v1ews:

Figure 1 1s a view in side elevation of my complete illuminating device or lamp shown connected with a section of a mud guard of a motor cycle; Fig. 2 is an enlarged sectional view on the broken dotted line shown in Fig. 3; and Fig. 3 is a front elevation of the device shown in Fig. 1.

Referring to, the details of the drawings, i represents a section of the mud guard of a motor cycle which is arcuate in form.

5 represents the base of my improved lamp the same consisting of a casting of the contour disclosed, hollow on its under side and having a flat outer wall and having its lower edges curved to conform to the curvature of the mudguard 4; to which it is secured by a series of bolts 6 which pass through suitable openings in the base 5 and in the mud guard, and are held bythe usual nuts placed on the under side of the mud guard, as clearly shown in Fig. 1.

Near one end of the base 5, arises the lamp body which consists of a tubular or cylindrical portion 5 from which extend outwardly flaring walls 5". In the top of the wall of the lamp body is an opening 5 which is guarded by an overhanging bridge portion 5 the sides of which project a substantial distance over the side edges of said opening so as to effectively exclude rain from within the body of the lamp, at the same time permitting the escape of heated air vtl'irough said opening. Further ventilation is provided in thelamp, by holes 5 in the bottom wall'opposite the opening 5 Extending from the lower wall of the lamp bddy 5 to the base 5, is an angular extension 5* which is drilled to provide a gas inlet which registers with a tip 13 cast integrally with said extension 5 An additional opening is drilled in said extension. at right angles to said inlet to receive a valve 12 which controls the passage of--the gas through said tip, to a burner tip 11 arranged within-the lamp body and suitably connected with the bottom wall of said body. 011 the outer face of the base 5 and projecting within the body a is a socket 8 to receive an electric lamp to which through saidsocket, lead conduit wires. The outer end of the body 5 is closed by a lens -10 secured in a frame 1O hinged at 10 to the lower side of the lamp lamp bodyextending across the flaring side walls is inserted a mica strip 9, which is secured in place in'a suitable slideway 5" in 'the top and bottom edges of the lamp body which flank the opening at thispoint'. The licensenumber or sign plate 12 is secured to a the flat outer face of the base 5 by the same bolts 6 which secure the latter to the mud guard 4. r

In Fig. 3 I have indicated by dotted lines a section oftubing connected-with the outer end of the tip 13, and it will be understood, that this tubing will lead to a'suitable supply of illuminating gas adapted to be burned at the burner tip 11 in the usual way, if the vehicle on which the lamp is erected, is supplied with gas. If, however,

' it has no gas tank but is supplied with suitable batteries, the lamp 7 will be used and theburnertip l1 may-be removed or may be left in position for use if desired at any time. While I have shown a hinged connection for the lens 10 it will be obvious that this may be dispensed with and the lens held in position on the lamp body in any manner which will permit its disconnection for the purpose of inserting new lamps 7 or lighting the tips 11.

From the construction illustrated and described, it will be apparent that rays of light emanating either from the lamp 7 or the tip 11 will be thrown upwardly and foropenings arranged in the walls of said lamp body so as to project'rays of lightin planes at an angle to each other, means for mounting an electric lamp in said body and means for mounting a gas burning tip in said body.

2. In a lamp, a sign carrying base adapt ed to be bolted to a suitable support, a tubular lamp-body integral with said base and extending at an angle to the plane of the base, said body having ventilating openings in its upper and lower walls, and

, my invention,

having a lens receiving opening in its outer end wall, and a light projecting opening at the junction of its upper Wall with said base, said opening having outwardly flaring end walls, a gas-inlet arranged at the junction of-the lower wall with said base, and integral with said wall and base, and a valve controlling said inlet.

3. In a lamp, a sign carrying base adapted to be bolted to a suitable support, a tubular lamp-body integral with said base and extending at an angle to the plane of the base, said body having ventilating openings in its upper and lower walls, means guarding the openings in the upper wall, said body also having an upward and outwardly flaring light opening, and a rearward light opening, a lens for said rearward light opening, a gas conduct-ing tip integral with said lamp body, a valve controlling said tip, and means for connecting a gas burner tip with saidlamp body.

4. In a lamp, a base adapted to he attached to a suitable support, a tubular lamp-body integral with said base and projecting directly therefrom, said lamp-body having ventilating openings therein and having a light projecting opening'at the junction of its upper wall with said base, said opening adapted to project rays of light from said lamp body along the top of said base and laterally therefrom, a burner arranged in said lamp body and means for conducting an illuminant to said burner.

5. In a lamp, a body adapted to receive a burner, and having light projecting walls and openings, and a base integral with said body, said base having an extensionto re- Y ceive and support asign in position to receive the rays of light projected from one of said openings.

6. In a lamp, a body adapted to receive a burner, and having light projecting openings, the walls of one of said openings being at an angle to the walls of the other opening, and all of said walls and openings so arranged as to project therays of light from said burner, a base integral with said body; and having extensions adapted to form an attaching bracket, and means for detachably connecting the bracket with a supporting structure.

In testimony whereof I affix my signature in the presence of two witnesses.
